This welcome title in the Your Carbon Footprint series prompts teens to consider the environmental implications of their lifestyles. A review of global warming’s causes and effects gives way to specific, planet-protecting choices, such as food purchases. The tone is occasionally strident: dry-cleaning “should be off limits,” for example. And lifestyle suggestions, such as cooperative housing, seem aimed at adults rather than at teens. Recommendations for community action (organizing petitions and boycotts), though, are on-target for a young audience, and the clear, focused information (illustrated with numerous color photos) will inspire and educate environmentally concerned young people. A glossary, bibliography, and resource lists conclude.
